Information:
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
There have been instances of diagnostic code E931 - Aftertreatment#1 SCR Dosing Reagent Absolute Pressure : Low (4334-18 - Aftertreatment #1 DEF #1 Pressure (absolute) : Low – moderate severity) becoming active. This code can be generated by a blocked 495-1507 Diesel Exhaust Fluid Filter Gp, due to the filter not being replaced at the correct maintenance interval.The maintenance interval schedule for the DEF pump filter is every 1500 hours. Ensure that the filter is replaced at the correct service interval. Refer to Operation and Maintenance Manual, Maintenance Interval Schedule for the correct procedure.
